Product Barcode

The Alcor by Tempest 86275 EGT/TIT Probe is a clamp-style, grounded Type K thermocouple probe designed for accurate exhaust gas temperature (EGT) or turbine inlet temperature (TIT) monitoring in reciprocating aircraft.

The 86275 uses a clamp mounting system for straightforward installation on exhaust tubing without requiring a welded probe boss. Its small-diameter sensing element provides rapid temperature response, while the built-in radiator helps protect the probe’s internal connections from prolonged high-temperature exposure.

The probe features 13.8-inch leads with reverse stagger configuration (long red lead / short yellow lead) and is designed for use with compatible Type K EGT and TIT instrumentation.
